What is a Tarlov Cyst?

Then there are others who have Tarlov Cyst Disease and TCs throughout the spine, at multiple or all levels. Their MRIs light up “like a Christmas Tree”! Unfortunately the higher cysts can not all be operated on at once because they are attached directly to the cord at multiple levels. Even if the patient attempted multiple surgeries, the likelihood of them reoccurring is much higher. The reason for this is that having multiple cysts means that the patient likely has a Connective Tissue Disorder (CTD) that allowed this condition to occur in the first place. Many patients have Elhers Danlos Syndrome (EDS) but there are hundreds of CTDs.
Many can be tested for with a blood test but there are many that can only be diagnosed by the symptoms of a patient. Having TCs throughout the spine would be considered such a symptom. Research is in its infancy right now, but one theory that is gaining traction is that some CTDs were likely triggered by a virus in the patient’s youth. There have been some indications that Epstein Barr Virus (EBV) could be associated, as could other viruses, but further research is needed.
EBV has been linked to other neurological diseases over the last couple of decades, such as MS. There is a theory that the EBV antibodies can hide dormant in the central nervous system (CNS) and could somehow break down certain proteins there, such as those in the myelin, causing MS, and even Connective Tissue in the Dura, which is one of the layers of the spinal cord that helps hold the CSF inside the cord.
I use the example of an old water hose that’s gotten weak, after years in the sun, breaking down its fibers. When the water is turned on, the hose bulges out in the weaker spots. Sometimes the hose even leaks water through the weakened material. The leaks can be major, spraying water everywhere, but sometimes the water just slowly seeps through the weakened, porous material.
You can push the water back into the hose and wrap the area with duct tape, but because the whole hose is weak, the likelihood of a new bulge popping out is very high.
This is likely what happens in the spinal cords of individuals that have multiple TCs throughout. The nerve roots bulge out with CSF, where the tissue is weakest. You can operate on them, and wrap them, one at a time, but the likelihood of a new one popping up is high. There can be other comorbidities in these patients too. Things like High CSF pressure (IIH), and CSF leaks in the weakest areas of tissue, Adhesive Arachnoiditis (AA), and even obscure symptoms that affect the organs that these nerve roots affect. For example, a patient may present with symptoms of a heart attack, but after thorough examination, the patient’s heart is fine. They may continue to have their “heart attack” symptoms without any understanding that it’s coming from the nerve root, sending wrong signals to the brain. This is called Cervical Angina and is usually caused by a pinched nerve, but since many doctors aren’t educated about TCs, they fail to see the connection. Any organ that is effected by the nerve root where the TC is located can cause symptoms. This is where a good dermatome Chart can come in handy.
Patients can feel like they have a UTI, yet none exists. They can feel like they’re having a stroke, where their face goes numb for a while, yet their arteries are fine. They can go from “ologist” to “ologist” for years before figuring out their true diagnosis, if it’s ever figured out at all. It IS important for those organs to be tested, in the event that it IS actually the organ but when all testing is clear, and they know that the organ isn’t the source, it’s good to know that the patient is actually experiencing symptoms and it isn’t made up or “in their heads”. There is hope for treatments, for both types of TC patient. Both surgical options for those with only a few TCs, and then there are non surgical options for those who aren’t ready for surgery or can’t have surgery for all of their cysts. My hope is that the medical community will continue to be educated about this disease because there are so many patients walking around with this disease, and it’s symptoms, that have wasted time and money as their disease progresses. They have had their physical suffering compounded by the mental suffering of being Gaslit and ignored. Many have lost their loved ones too, because if the doctor says “you’re fine! There’s nothing wrong with your ___.” why should their family believe them? Especially when it lasts for years. It’s devastating to so many people and families and it’s not necessary! The research has proven that they can be symptomatic. Unfortunately, many doctors only recognize them after they’ve become catastrophic and permanent damage has been done. Early recognition and some simple treatments could prevent them from becoming catastrophic! It could give people hope and recognition. I know that when I finally figured out what was wrong with me, on my own, I was NOT scared. I was overjoyed! I was vindicated! I wasn’t faking it or losing my mind! The next part of the journey, to educate myself and my providers, was difficult, and still can be, but it was nothing compared to the decades of not knowing why, and having doctors dismiss me and Gaslight me.




Thank you so much for this blog post. You mentioned that “early recognition and some simple treatments can prevent them from becoming catastrophic” , could you further comment based on your experience on what simple treatments could help?
